New Delhi: Central security agencies have traced the alleged threat mail received by Gurgaon-based five-star hotel Leela Kempinski to a cyber cafe in Kolkata.

The sources said the threat mail claiming to be from terror group Indian Mujahideen has been traced to a cyber café Kundu Computers in Behala area of Kolkata.

They said prima-facie the mail looks like a prank but further investigations are on. They said the cyber cafe does not have close circuit cameras installed or any log register. The hotel had recently made a complaint to Delhi Police alleging that it had received a mail threatening to carry out 26/11 like attacks. The mail claimed it was from Indian Mujahideen.

The sources, however, said a Bengali surname was linked with the email address which led to suspicion that it could be a prank. They said further investigations are being carried out to ascertain the sender of the mail.
